  • Patent number: 8411565
    Abstract: A broadband local area data network uses coaxial cable wiring for interconnection of terminal devices. Orthogonal frequency division multiplexing (OFDM) with bit loading is used to overcome channel impairments and provide a path for terminal devices to transmit to and receive from other terminal devices. Probe messages are sent between devices to characterize the communication channel and determine optimum bit loading. The data network shares the cable spectrum with other services and uses frequency bands not used by other services. Adaptive power control can be used to maintain signal to noise ratio in a communication between terminal devices. Frequency coordination can be used to avoid interference between the LAN communications and other services transmitted on the cable.

  • Patent number: 8351382
    Abstract: A persistent or a semi-persistent uplink resource allocation also includes an indication for a user equipment UE to send channel quality reports. The format for the channel quality report is determined (based on a transmission mode for which the UE receives a downlink shared channel). In at least first transmissions of user data for instances of the persistently allocated uplink resource the UE sends user data and a channel quality report according to the determined format. For the case that a NACK is received in reply to one of those sent user data with channel quality reports, four options are detailed: re-send the NACK'd user data on a next instance of the persistently allocated UL resource with or without a channel quality report, and re-send the NACK'd user data on a dynamically allocated uplink resource with or without a channel quality report.
